A reciprocating compressor has been selected to compress 0.085 m3/s of 25oC methane gas from 100 to 6200 kPa. Assuming that the heat capacity remains constant at 2433 J/(kg?K) over the temperature range of compression and that the ratio of C p/C v remains constant at 1.31. How many stages of compression should be used if the compression ratio is smaller or equal to 5. What is the power requirement if the compressor exhibits an efficiency of 80 percent? What is the exit temperature of the gas at the exit from the first stage? If the temperature of the cooling water can only increase by 15oC, how much water is required for the intercoolers and after cooler to ensure that the compressed gas from each stage after cooling is again returned to 25oC?
